However, Queensland Education Minister John-Paul Langbroek threw a spanner in the works on Thursday morning, telling ABC radio there was no point in further negotiations and calling Prime Minister Kevin Rudd a charlatan.

The prime minister on Wednesday repeated calls for Queensland to stop playing politics and get on board.

"Bill Shorten can come on to your show with his velvet tones and try to make out that he's offering us a lot more and that he wants to sit down and talk, while his boss is out there slagging us in a press conference," Mr Langbroek said.

Mr Shorten has conceded there appeared to be "some scratchiness" in negotiations.

He has offered to fly to Queensland to meet with the minister and premier.

"In the politest and gentlest possible way (I) say to them, when you've got another level of government offering to provide two extra dollars for every extra dollar that you invest in children's education in Queensland, this is a good deal."

Mr Shorten reiterated the federal government had no interest in taking over the running of schools in any state.
